Stable LM 2 1.6B
Stability AI's compact 1.6B multilingual model trained on 2T tokens.
About
Stable LM 2 1.6B is the inaugural model of Stability AI's Stable LM 2 series, released in January 2024 in both base and instruction-tuned versions. Trained on 2 trillion tokens across English, Spanish, German, Italian, French, Portuguese, and Dutch, it was positioned as one of the most capable sub-2B models of its time.
Stability AI published unusual transparency artifacts alongside it, including the final pre-training checkpoint before cooldown and optimizer states for continued training. The model is available for commercial and non-commercial use through a Stability AI membership rather than a plain open license, which users should factor into adoption plans.
